Methods and apparatus for jewelry

ABSTRACT

Methods and apparatus for jewelry may comprise a locket system comprising first and second portions that may be attached to define an interior cavity. The locket system may also comprise a seal adapted to seal the interior cavity.

BACKGROUND OF THE INVENTION

The present invention generally relates to a modular interchangeable jewelry system and specifically to a modular interchangeable jewelry system comprised of one or more interconnecting and exchangeable modular components.

BRIEF BACKGROUND

Human use of jewelry extends beyond memory, tradition or recorded history. Throughout recorded history, jewelry has been used for many purposes. Like painting or poetry, jewelry may be used as a form of expression or assertion of a user's personality, feelings or ideas, demonstrating the uniqueness of a user. Jewelry may simultaneously be used to provide a functional way of storing personal effects in a meaningful way.

Jewelry is generally designed to form a single invariable unit of static design, preventing a user from customizing the jewelry to different parts of the user's body, or to serve different functional purposes. While various modular jewelry designs, including lockets, have been proposed in the prior art, much of the prior art focuses on either functionality or artistic need but not both.

A need exists for a customizable jewelry system with interconnecting and exchangeable modular components adapted to substantially easily attach and detach to and from any one or more of the other modular components in matter of seconds without any particular training, tools, or effort, while still fulfilling a desired functional purpose. A customizable jewelry system allows the user to build or alter the various modular components according to individual or personalized specifications and functions.

BRIEF SUMMARY OF THE INVENTION

Methods and apparatus for jewelry may comprise a locket system comprising first and second portions that may be attached to define an interior cavity. The locket system may also comprise a seal adapted to seal the interior cavity.
